Great find on the'64. I have that power steering system on my 1811 and love it. My 1811 also would creep faster and faster but it turned out to be the friction nut on the go lever at the bottom of the stalk. Good advice on the fuel system. I have found the only issues I have had with mine is with the fuel system or a couple of the stupid safety switches causing electrical gremlins. I have replaced many axle seals on the small John Deeres and it is not a big deal. There are a couple of things to watch for and if you really pay attention to where everything is BEFORE you take it apart, like depth and direction, you won't have any trouble replacing them. Since you will be draining all of the tranny fluid out have the new filter and oil ready when the job is finished. I don't know how the '64 tranny fluid is changed but if it is like the '11 then now would be the time to add the big mouth filler that Xtreme sells.Good luck with your new toy.
